A kind of novel magnetosensitive temperature controller brake apparatus
Technical field
The utility model relates to the temperature controller brake apparatus, more particularly, relates to a kind of novel magnetosensitive temperature controller brake apparatus.
Background technology
Existing market serviceability temperature controller is the bimetal leaf structure; Because the requirement on machining accuracy of bimetallic material is high; Heat-treat condition is relatively harsher, so qualification rate is low in this process of producing product, and the main dependence on import of bimetal leaf sheet material; Price is high, and temperature-controlled precision is relatively poor, corrosion-resistant, be prone to get rusty and cause losing efficacy.
The utility model content
The utility model technical problem to be solved provides that a kind of temperature control is highly sensitive, stable performance, novel magnetosensitive temperature controller brake apparatus that temperature-controlled precision is high.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of novel magnetosensitive temperature controller brake apparatus, it comprises shell; In said housing, be provided with soft magnetism and below soft magnetism, be provided with Hard Magnetic; Be provided with on spring and this spring termination Hard Magnetic under termination soft magnetism and this spring between said soft magnetism, the Hard Magnetic; Close contact has thermal conductive shell above said soft magnetism, and a pull bar stretches in the shell by said outer casing bottom and is connected fixing with said Hard Magnetic.
Said Hard Magnetic is a center Hard Magnetic with holes, and said pull bar is fastened in the Hard Magnetic hole.
Said soft magnetism is processed by temperature sensitive magnetic material.
The utility model is owing to adopted said structure; Contacting afterwards through two magnetics of soft magnetism and Hard Magnetic, magnetic conduction produces the magnetic force of inhaling mutually; Make length of spring compressed, magnetic conductivity loses and loses the magnetic force of inhaling mutually when soft magnetism arrives operating temperature point (Curie point), and the active force that spring produces breaks off the mains switch of heating container through mechanism's bar of heating container; Cut-out is to the heater element power supply of heating container, thus the break-make of control entire circuit.So the utility model temperature control is highly sensitive, stable performance, temperature-controlled precision are high, in addition, according to the characteristic of soft magnetism, its temperature control scope is wide, is approximately-80 ℃~280 ℃.
After the detailed description of the execution mode that combines advantages the utility model, it is clearer that characteristics of the utility model and advantage will become.

Wherein: 1. thermal conductive shell, 2. soft magnetism, 3. spring, 4. Hard Magnetic, 5. pull bar, 6. shell, 7. mechanism's fulcrum, 8. mains switch, 9. electric heating vessel heater element, 10. mechanism's bar.
Embodiment
With an execution mode the utility model is done further detailed explanation below, but should explain that the protection range of the utility model is not limited only to this.
Consult Fig. 1, Fig. 2, a kind of novel magnetosensitive temperature controller brake apparatus, it comprises shell 6; In said housing 6, be provided with soft magnetism 2 and below soft magnetism 2, be provided with Hard Magnetic 4; Soft magnetism 2 is processed by temperature sensitive magnetic material; Between said soft magnetism 2, Hard Magnetic 4, be provided with termination soft magnetism 2 and 3 times termination Hard Magnetics 4 of this spring on spring 3 and this spring 3, wherein, the suction of soft magnetism 2 and Hard Magnetic 4 will overcome the elastic force that spring 3 compressions produce; Close contact has thermal conductive shell 1, one pull bar 5 to be stretched into to be connected in the shell 6 and with said Hard Magnetic 4 by said shell 6 bottoms to fix above said soft magnetism 2.Wherein, spring 3 can replace with shell fragment.In addition, mains switch 8 can be sensitive switch.
In this execution mode, band Hard Magnetic hole, said Hard Magnetic 4 center, said pull bar 5 is fastened in the Hard Magnetic hole, and wherein, Hard Magnetic 4 can be fixed together through snap ring or alternate manner with pull bar 5.
Consult Fig. 3, when this execution mode specifically used, thermal conductive shell 1 had good thermo-contact with the heating container; The pull bar 5 of this execution mode connects with mechanism's bar 10 of heating container, then, press the mains switch mechanism of heating container after; Mechanism's bar 10 moves upward pull bar 5, is pulled together through the magnetic force that the magnetic conduction effect produces adhesive up to Hard Magnetic 4 and soft magnetism 2, and spring 3 is compressed simultaneously; Mains switch 8 rapid closings, this moment, entire circuit was connected, and heater element 9 is started working; Soft magnetism 2 is heated, and when surpassing the needed temperature of heating container, magnetic conductivity lost and loses the magnetic force of inhaling mutually when soft magnetism 2 arrived operating temperature points (Curie point); The active force that spring 3 produces makes mechanism's bar 10 rapid disconnecting power switch 8 through pull bar 5, cuts off the heater element power supply to the heating container, thus the break-make of control entire circuit.
Though described the execution mode of the utility model in conjunction with accompanying drawing; But those skilled in the art can make various distortion or modification within the scope of the appended claims; As long as be no more than the described protection range of the claim of the utility model, all should be within the protection range of the utility model.
